The Resume-MailboxDatabaseCopy cmdlet resumes replication and replay from a suspended state. If a database copy was suspended without administrator intervention, it's because the database copy is in a bad state. You can use the Get-MailboxDatabaseCopyStatus cmdlet to see if there are any messages indicating a failure. If the copy of the database is in a bad state, resuming the copy causes replication to fail and the mailbox database copy to return to a suspended state.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Database availability groups" entry in the High availability and site resilience permissions topic.

The DisableReplayLag parameter specifies that any configured replay lag time for the database copy should be disabled when the passive copy is resumed.

Identity

Required

Microsoft.Exchange.Configuration.Tasks.DatabaseCopyIdParameter

The Identity parameter specifies the name of the database whose copying is being resumed.

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.

DisableReplayLagReason

Optional

System.String

The DisableReplayLagReason parameter is used with the DisableReplayLag parameter to specify an administrative reason for disabling replay lag time for a passive copy.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.

ReplicationOnly

Optional

System.Management.Automation.SwitchParameter

The ReplicationOnly switch specifies whether to resume replication without affecting the activation setting (for example, the ActivationSuspended property for the database copy remains set to True).

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
